INSULATING CONTAINER AND THE LIKE.

Patented July 4i, i922.

Application led October 2U, 1919. Serial No. 331,796.

will be readily understood by those skilled' in the art, in the light-of the following explanation of the accompanying drawings illustrating what I now believe to be the preferred embodiment or mechanical expression of my invention from among other forms, constructions and arrangements within the A spirit and scope thereof. 2a Y 1t is an object of the invention to provide a container for holding a receptacle such as a fruit jar, paper package, Yor the like, containing food-stuffs for example,'with a minimum change of, temperature in the receptacle while in storage or transportation.

A further object of the invention is to provide a container for this purpose, in which the receptacle placed therein will be spaced from-the walls/of the container to provide dead air spaces about the receptacle, with a c minimum contacting surface between the container and the receptacle, thus materially reducing the transmission by induction of heat or cold from the receptacle to the container.

A still further object of the invention is Ito provide a container of simple and inexpensive construction, which preferably may be formed entirely of stiff paper adapted to be readily cut, and wound into tubing upon paper-working machines of standard or any preferred construction, thus providing a container which may be readily manufactured without the use of machinery other than that to befound in any plant given to the manufacture of paper articles.

With these and other objects in view,\the invention consists in certain novel features in construction, and in combinations and arrangements as more fully and particularly set forth and specified hereinafter.

Referring to the accompanying drawings:

Fig. 1, is a vertical section through a package constructed in accordance with my invention, showing a receptacle, instanced as a glass jar contained therein.

Fig. 2, is a top plan view of the same with the cover of the package removed.

Fig. 3, is a perspective view of the various elements which when assembled go to form the package or container.

Fig. 4, is a similar view of the parts forming the` cover for the package.

In the preferred form, I have shown the container as comprising an outer casing l, instanced as formed of paper preferably shaped into a cylindrical tube by winding a strip 2 of the same upon a paper-'tube winding machine.

The base of the casing is shown as a paper disk 3 received within the lower end of the cylinder, with the lower edge portion i thereof,' crimped upon the downwardly bent outer edge portion 5 of the disk as shown at 6 in` any preferred manner, as well understood in this art.

A falsevbottom is received Within the cas ing, spaced from the base to form a dead air space 7 which acts as a heat insulating medium for the receptacle received within the container. This false bottom is shown as a paper disk 8, tting snugly within the cylindrical tube, and instanced as resting upon a `tube 9'supported upon base 3, thus spacing upper and lower edges, t-hus reducing to a minimum the transmission of heat by induction from the false bottom to the outside of the container.

The receptacle supported within the container upon the false bottom, and shown in the drawings as a glass jar 10,'although it will be obvious that any receptacle may be so carried, is preferably of substantially less cross-sectional area than the container so that when centrally positioned within the same. a dead air space l1 is formed between the side-walls of the container and the re ce tacle.

i cans are provided for centrally disposing thereceptacle Within the container, so as to maintain this air space completely around 'container and secured in spaced relation i thereiiftheirings preferably being of such ing widtlira's. to space the vreceptacle a substantial distance from the side walls of the container.

- Theserings Vand the false bottom of the container, may be held in position by spacjacent rings, and between the upper and lower ring and the top and false bottom of the container respectively. The spacing members are preferably formed of strips of paper'14 wound into cylindrical tubes. The

. spacing member at the top of the casing above the upper ring is vpreferably of such width as to terminate short of the upper edge of the casing, forming a shoulder 15 against which the lip of the closure for the container is adapted to abut as will be hereinafter described.

`A closure having a dead air space formed therein is provided for the container. This closure is instanced as comprising a wound paper tube 16 having a disk 17 crimped over its upper end, as by having the edge 18 of the tube bent back and crimped upon the upwardly bent outer edge 19 of the disk, in a Well known manner. 4

A false top is provided'within the'closure space 20. This falsetop is shown as a disksitioned between a spacing member shown -as a wound paper tube 22 fitting within the fclo'sure, and received between the false top and the endl disk; and a retaining member, exemplified as a wound paper tube 23, which fits snuglyagainst the inner surface of the side walls of the closure below the false top.

The retaining member 23 may extend below the lower edge of the tubingforming the closure, to provide a lip 24, adapted to be received within the open end of the casing i forming the container, this said lip resting upon the shoulder 15 formed Afor that purpose at the mouth of the container.

' In assembling the container as thus de scribed, the various parts may be glued together wherever necessary, and the entire container may, ifA desired, be treated with paraffine or other moisture proof substance. In lpractice it will be found desirable to employ a container with an inner receptacle of less cross-sectional area than the openings in the annular members positioned upon the inner surface of the side walls of the container, so that the inner receptacle will only members 13 shown as fitting snugly, against the inner surface ofthe side walls f. of `the container, and disposed between ad# spaced from the end disk to forma dead aircontact with these annul ar members throughout a part of its circumference, thereby still furtherI reducing` the transmission of heat from the receptacle through the annular members.

For a similar reason, an inner receptacle is preferably employed which is of such height as to not contact with the false 'top of the closure for the container. o, f y Bythe construction as thus described, it will be seen that I have provided a container for a receptacle, in which the' inner receptacle is completely surrounded by dead air spaces forming heat insulators, the points of contact between the inner receptacle and the container being reducedqto a minimum to prevent'the transmission of heat by induction.

I have thus provided an 'inexpensive and efficient method for-the storage and transportation of food-stuffs and the like, the Y.
